INTRODUCCIÓN

Esta actividad es desarrollada para culminar el ciclo del diplomado en CCNA cisco, donde se logra la solución de los dos escenarios

correspondientes a la guía correspondiente “prueba de habilidades prácticas”, tomando como punto de referencia la rúbrica de la

DESARROLLO DE LOS ESCENARIOS ESCENARIO 1

Este escenario plantea el uso de RIP como protocolo de

enrutamiento, considerando que se tendrán rutas por defecto redistribuidas; asimismo, habilitar el encapsulamiento PPP y su autenticación.

Los routers Bogota2 y medellin2 proporcionan el servicio DHCP a su propia red LAN y a los routers 3 de cada ciudad.

CONCLUSIONES

De acuerdo con los contenidos vistos dentro del curso Diplomado de Profundización Cisco CCNA, se logra conceptualizar con claridad el término red, que es un conjunto de dispositivos conectados por medio de cables, ondas, señales, y demás métodos de transporte de datos para compartir información y servicios.

En esta actividad se realiza un numero amplio de tareas importantes para el buen desarrollo de los ejercicios propuestos, en este se

ejecutan funciones como la de verificar una conexión entre los

dispositivos proporcionada en la configuración inicial de la topología, se configura la ACL de los Routers, esto con el objetivo de mitigar los ataques de forma remota y por supuesto no podrían faltar la

verificación de la funcionalidad de las actividades ejecutadas con anterioridad. (ACL) para permitir el acceso de direcciones IP específicas, lo que asegura que solo la computadora del

administrador tenga permiso para acceder al router mediante telnet o SSH.

En la configuración NAT y PAT se tiene niveles de seguridad

importantes, pues un router ISP solo puede responder solicitudes mas no puede hacer solicitudes a los hosts que conforman una red privada, pues no conoce sus direcciones IPs.

NAT necesita información de la IP o a información del número del puerto en la cabecera IP y encabezado TCP de paquetes para traducción; además hay una lista parcial de protocolos que no se pueden utilizar con NAT, por ejemplo, LDAP, SNMP, Kerveros versión 5; también encontramos que NAT tiene otra desventaja la cual es que se retrasa en el proceso de traducción.

Cuando tenemos Routers separados DHCP para cada subred estamos agregando más complejidad y decrementamos la administración central de la red. Requiriendo que cada Router trabaje para sus propias direcciones DHCP, teniendo como función primaria el tráfico del ruteo y siendo más fácil de administrar.

PAT resulta más sencillo de implementar que NAT debido a que solo es necesario especificar el puerto a la red externa para realizar la traducción de direcciones IP privadas a públicas y no un rango de direcciones.

El tiempo de vida o TTL de los paquetes que se envían de una red LAN a otra es mucho menor que el TTL de los paquetes que recorren una misma red debido a que tiene que atravesar R1 y R2.

TTL de paquetes entre los dispositivos de una misma red LAN es 127 ms mientras que el TTL de los paquetes entre los dispositivos de diferente LAN es 126 ms. Para la asignación de subredes IPv6 es importante conocer la conversión de números Hexadecimales.
